not a method. which can always be practiced satisfactorily by those notespecially skilled, and: besides it; requires considerable. time. Alsothere is a'considerable proportion 'of each plate'left blankwhi'clrrepresentsi so much Waste in' material and unnecessary Weight,both :of which: are important con siderations in large lists.

: My inventioniprovides aznovel method for makingprinting plates having:a single. line, as showir'in the drawing, or having a; pluralityaoffilines, each plate adapted to; be detachahlyengaged withandwheldi byrretainingydevices onfithe frame. "The 'blank 15. for:making the plate is made: ofisuitable sheet materialvot a kind whichwillvenable printing characters to be embossed thereon, and which iswelliknown' in the" art. This blank may; be of. any size, andit'isidividedinto. panels 16by parallel scoring 17'oneiits .face and 18 on its back.Thescore lines on the back are opposite the score lines on the frontthey are preferably v shaped as shown in Fig, 2,.and1'they cutintotheY-blank toia suflicient idepth. so that the panels may 'beeasilyseparated bypressure of the; fingers but are" connected togetherso that thebl'ank can be ehandled without accidental separation orthetpanelsr The margin panelsll6 arewof-"suifici'ent width toaccommodate the jawswhich hold them in the embossing machine, and whenthe embossing operation is -compl'eted they are broken oiirand:discarded. "The type panels 16 between the margin panels 16 are narrowbut of suitablewidth for the type characters 'so that the embossedpanels can be mounted on i the frame in proper line spacing. It isifound in practice' 'thatthe type lines can be embossed: on the blank,Fig. 7 invusualiiline spacing-and still leave enough materialist themargins of eachtype line'panel forengagementwith the retaining deviceoni the. frame. It is difficult to represent the exact dimensions andproportions in the pen and ink'drawings,;but =ll3Wlll be understood thatthe object is to have each panel as narrow as the enibossingoperationwill permit with.-

out distortingorbreaking the metalvin the r embossing. operation, andin; practice has been found that the printing characters may be embossedin several lines on a scored plate and in close line spacing, and thetype line panels may be separated and mounted in a frame in line spacingforaddressing. It may be that the scoring permits the metal to flow moreeasily in the embossing opera tion without distorting or breaking theplate. However, this may be, I do know that type characters, upper andlower case, can be embossed in several lines, in proper type spacing andline spacing, and when the panels are separated on the score lines eachpanel has sufficient side margin for operative engagement with retainingdevices on the frame, these devices being arranged in close line spacingor otherwise, as desired. The

retaining devices are lips struck up from the frame 9 in pairs of rows.The lips 19 of the upper row of each pair are inclined downwardly, andthe lips 20 of the lower row of each pair are inclined upwardly, Fig. 5,to provide an angular groove under each row of lips, discontinuousbecause of the spacing of the lips, to receive the top and bottom edgesof the panel, and these edges may be tapered by reason of the scoring,as shown in Fig. 4, to more easily fit under the lips. The panel islight in weight, and

it is only necessary to provide a slight edge engagement with theretaining lips to hold the panel on the frame. Thus it is possible toform the type characters close to the edges of the panels, because onlya slight projection of the panel beyond the type is required forengagement with the retaining lips; and in the V-shaped form of scoringshown, which I prefer, the extremity of the beveled edge is suflicientto effect this engagement. It will be understood, of course, that inactual practice the blank is quite thin, and the scoring is necessarilysmall transversely, but it is sufiicient to enable the panels to bereadily separated without liability of distorting the panels.- The lipspermit the panels to be inserted endwise and the use of light gaugemetal for the plate blank; the inclined lips, forming discontinuousguide grooves for engagement of the tapered edges of the panel, enablethe panel to be readily inserted and removed from the retaining devicesof the frame or to be adjusted to any desired position.

WVhereas it has been customary heretofore to emboss an address or otherform on a single printing plate, which leaves a considerable portion ofthe plate blank, representing waste material and unnecessary weight inthe complete printing device, with my invention the panels may beembossed for their full length and divided as required after separationfrom other panels so that all, or substantially all, of each panel. maybe employed far embossing, The type panels may be adjusted to anydesired position on the frameto pro- ,material, made, up at the factoryand supplied to the customer, or made up by the customers operator atodd times; and such stock material may be kept in storage for use asrequired, or it may be set up in frames for use as required. When aprinting device is to be discontinued for any reason, the name andstreet address type panels may be removed and destroyed, the frame andthe city and Salutation type line panels being preserved for furtureuse. Thus the invention reduces the cost and expedites the work ofmaintaining a list.

I have shown and described a printing plate blank and method of usingthe same for making printing plates adapted for use in a frame forming acomplete printing device in accordance with my original lnvention, but Ido not limit this invention to this particular use or adaptation, andreserve the right to practice the invention in making printing plates ofany other kind and for any other purpose within the scope of thefollowing claims:

I claim:

1. A blank of suitable material in which printing characters may beembossed to form a printing plate, said blank having oppositely disposedscore lines dividing the blank into one or more panels on which printingcharacters are embossed with the character impressions located close tothe score lines,

and a marginal panel adapted to be gripped 1 by the jaws of theembossing machine for holding the type panel in position to havecharacters embossed therein.

2. A blank of suitable material in which printing characters may beembossed to form a printing plate, said blank having oppositely disposedscore lines dividing the blank into a. plurality of panels on whichprinting characters are embossed with the character impressions locatedclose to the score lines, and a marginal panel at each side of theplurality of type panels, either of said marginal panels adapted to begripped by the jaws of the embossing machine for holding the blank witha type panel in position to have characters embossed therein.

3. The method of making a printing plate which consists in providing ablank, scoring the blank in parallel lines on opposite sides with thelines on one side disposed opposite the lines on the other side to formnarrow type panels, embossing printing characters on the panels With thecharacter impressions I located close to the score lines, and thenseparating the panels on the score lines whereby the embossed panelsareprovided with beveled edges to engage retaining means so that aplurality of embossed panels may be closely assembled to form a printingform with close line spacing.

4. The method of making a printing plate which consists in providing ablank, scoring the blank in parallel lines on opposite sides with thelines on one side disposed opposite the lines on the other side to formnarrow type panels, embossing printing characters on said panels withthe character impressions located close to the beveled edges of thepanel, and then separating the panels on thescore *0 lines.
